SPECIFICATION forming part of Letters Patent No. 476,212, dated May 31,1892.

Application tiled April 20, 1891. Serial No. 389,687. (No model.)

To @ZZ whom t may concern:

Be it known that I, SILAS H. RAYMOND, a citizen of the United States,residing at Grand Rapids, in the county ot' Kent and State of Michigan,have invented certain new and useful Improvements in Oarpet-Sweepers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to 1o which it appertains to make and use the same. My inventionrelates to improvements in carpet-sweepers; and its objects are to pro-Vz5 line w wot Fig. 2.

Like letters refer to like parts in all the figures.

A is the case; B, the bail, having iexible arms embracing the case andterminating in 3o disks D, having central openings engaging studs O onthe bail-plates O and having washers O, of some soft material likerubber or leather, interposed between said disks and bail-plates toincrease the friction'and pre- E is a pendent arm attached to saidbail-plate, having a downwardly-open bearing in its lower end, in whichis removably secured the journal Gr of the brush-shaft G by means of aspring F, at-

4o tached at its upper end to said pendent hanger and having an openingnear its lower end which engages the end of the said journal. By bendingsaid spring outward at its lower end the brush-shaft is released and canbe removed from the said bearings.

I are the driving-wheels, having a single radial flange I at the outerangle of the rim and a soft-rubber rim I', which engages said iiange Iat the rear and surrounds said `wheel. By providing but one flange Ifind 5o said rim is easier placed in position and removed,while stillsuftcien tly retained in place. Said driving-wheels engage the iloor andpulley II on the brush-shaft and `are journaled on studs J, attached tothe curved levers K, 5 5 which levers extend diagonally outward andupward at their outer ends and are pivotally secured to the end wallof-the case by screws or studs L, which pass through horizontal slots Min said levers to permit of horizontal, 6o while preventing vertical,motion of the ends of said levers. Said levers K are also prolongedinward and upward in a curve and meet at a point midway and above thebrushshaft, where they are pivoted to each other. By this constructionany unequal pressure upon the respective driving-wheels due to thediagonal direction of the thrust upon the handle attached to the bail Bis at once equalized upon both of said driving-wheels and the 7o casesinks downward equally at both sides. As the inner ends of said leverswill rise vertically and the outer ends move horizontally upon thescrews L and the studs J move diagonally inward and upward the rims Iwill be compressed equally against the pulley I-I.

What I claim isl. In a carpet-sweeper, levers having the driving-wheelsjournaled thereon, said levers y 'pivoted to the case and horizontallymovable 8o thereon at their outer ends and pivotally attached to eachother at their inner ends, substantially as described.

2. In acarpet-sweeper, levers having studs upon which the driving-wheelsare journaled, said levers being extended from said studs diagonallyupward and outward and having horizontal kslots near their outer ends,and screws passing` through said slots and attached to the case, saidlevers also `extended inward 9o and upward and pivotally connected toeach other, substantially as described.

In testimony whereot` I affix my signature in presence of two witnesses.
